I just noticed something. There are users who only compete for lowest times. They clearly quit games they get stuck on so as not to increase their times beyond a very low number. This month, I unknowingly left a puzzle unsolved when I was trying to do something for admin under a different username. I must have done something incorrectly while switching back and forth. When I saw the puzzle the next morning, I immediately solved it. But, of course, it blew up my average solving time. I have recovered to a competitive level by solving more puzzles. However, if one competes for success rate challenge, they have to accept less than stellar times in the course of solving all puzzles. Perhaps we should have different solve time competitions for users who complete all their puzzles. This seems a fair solution for all.
Thanks,
